Methods and apparatus for supporting network access using cable and radio communications links

ABSTRACT

Both wireless communication and communications via a cable modem are supported between a network node and a customer premises. Alternative communications links provide redundancy and the possibility to take advantage of the different types of links capacity to provide a level of service that would not be possible using a single communications link to a customer premises. In various embodiments a network node, such as a cable network node hubsite, has an optical connection to the Internet or another communications network and provides network access to one or a plurality of customer premises. The network node includes a wireless access point, e.g., pole mounted base station, as well as one or more cable modem interfaces to thereby allow for both wireless and cable modem based communications. This allows for packets of different applications to traverse different links and/or to switch between links in the event of maintenance or reliability issues.

FIELD

The present application relates to communications systems, and more particularly to methods and apparatus hybrid communications systems in which cable and wireless communications links are supported.

BACKGROUND

Cable modem interfaces to the customer premises provide a reliable communications link with predictable transmission characterizes in many cases. While more recent cable standards have the promise of providing more symmetric data rates and/or higher data rates than current cable standards it is expected that many cable system deployments will continue to have asymmetric data channels with the uplink being considerably more limited that the downlink for many years to come. Accordingly, for some application such as HD video creation applications where a user may want to upload a large amount of data, currently deployed cable communications networks which use cable modems may have difficulty handling the large upload demands of HD video content and/or other data intensive applications where a user needs or desires to upload large amounts of data, e.g., for delivery to a content distribute or another party.

While upload limitations are one issue, another issue with relying solely on a cable modem based communication link as the sole communications link to a customer premises is one of resiliency. While cable modems are highly reliable, components associated with data communications over cable modems may suffer from failures, degradation and/or other issues resulting in the degradation of the ability for a user at a customer premises to communicate over the cable modem based communication link or have difficulties with such communications.

In addition to communications problems relating to component failure, in some cases maintenance may be required on one or more components of a cable modem system. In cases where the cable modem link is the sole communications link to a customer premise service may be interrupted for a period of time when one or more components associated with the cable modem communications link need to be replaced or serviced. Loss of complete data communications for even a short period of time for a business or residential customer can be traumatic and it is often highly desirable to avoid such a total loss of service even if it is for a brief scheduled maintenance period.

SUMMARY

In various embodiments both wireless communication and communications via a cable modem is supported between a network node and a customer premises. The dual alternative communications links provide redundancy as well as the possibility to take advantage of the different types of links capacity to provide a level of service that would not be possible using a single communications link to a customer premises.

In various embodiments a network node, such as a cable network node hubsite has an optical connection to the Internet or another communications network and provides network access to one or a plurality of customer premises. In at least some embodiments the network node includes a wireless access point, e.g., base station, as well as one or more cable modem interfaces to thereby allow for both wireless and cable modem based communications with one or more customer premises. The base station may, and sometimes does, include a pole mounted antenna, e.g., telephone or light pole mounted antenna, through which the network node can wirelessly communicate with one but often multiple customer premises in an area. Directional antenna beams may be, and sometimes are, used to support a high rate of communications, e.g., gigabit communications, with the customer preemies. The wireless interface can support symmetric uplink and downlink communications or asymmetric communications with, in some cases, the uplink channel supporting a higher data rate than the downlink wireless communications channel to a customer premises. The customer premises may, and often do, include an external antenna with a direct line of sight to the base station antenna.

For purposes of discussion it should be appreciated that customer premises may, and sometimes do, include residential premises but in other cases the customer premises include business premises such as in an office park. In fact, in the case of business where communications is critical to the success of the business, the methods and apparatus are particularly well suited as they provide a high degree of resiliency and service than in the case where cable modem communications is solely relied upon.

In various embodiments the network node includes a scheduler for scheduling use of communications links between the network node and the one or more customer premises to which the network node is coupled, e.g., wirelessly and via a cable modem interface. For scheduling purposes wireless and cable modem links are treated as alternative communications links with uplink and downlink communications being scheduled over each of the different types of supported links. The scheduler makes a joint scheduling decision on an individual customer basis taking into consideration the applications, e.g., voice, HD video content creation, Web Browser and/or other applications running at a customer premise. Uplink and/or downlink traffic for a customer application is scheduled over the wireless or cable modem link depending on a variety of different types of information including link quality information, the amount of data to be transmitted in a given direction, planned maintenance information, etc. The scheduler communicates to the customer premise device at a given location, e.g., an integrated network device including a cable modem and wireless interface, a schedule to be used in determine which communications link to use to transmit data corresponding to a particular application at a given time. Uplink and downlink traffic data may be, and sometimes are, transmitted over different links for the same application. For example, for video content creation applications a high capacity wireless communications link may be used for a period of time to upload content while downlink traffic such as acknowledgements from a device to which the content is transmitted via the Internet may be communicated over the cable modem interface.

While under normal conditions the scheduler may exhibit a preference for transmitting data corresponding to some types of applications over one type of link than the other, in at least some embodiments link quality is monitored and the scheduler takes into consideration changes in link quality and thus the reliability and/or bandwidth available over a given link. In some embodiments the customer premises device reports downlink quality information for both the wireless communications link and the cable modem communications link to the network node. In some embodiments the communications link quality information is transmitted over the wireless or cable modem link to which the information relates while in other cases link quality for one type of link is communicated over the other link. For example in some embodiments cable modem link quality is fed back over the wireless communications link in addition to wireless link communications quality. The link quality information may be in the form of an error rate, interference measurement and/or some other channel quality metric. In the case of a detected link failure, the failed link is reported over the link which remains intact. For example if failure of the cable modem link is detected by a customer premise device is detected, in some embodiments the failure and related diagnostic information is communicated back to the network node via the wireless link to the customer premise device. Similarly, if a wireless link or hardware failure is detected at the customer premise, the failure and related diagnostic information is reported via the cable modem link. Failures detected at the network node are similarly communicated to a customer premise device via the remaining link. While downlink quality is often measured at the customer premise device uplink quality is normally measured at the receiving device of the network node, e.g., at the wireless receive or cable modem of the network node.

The scheduler takes into consideration changes in link quality, loading and or other factors in generating an updated communications schedule for the customer premise or premised coupled to the network node. The update schedule for a customer premise is communicated to the customer premise device at an individual customer premises and used to determine which link packets are to be transmitted and/or received on for a particular application. As link quality changes or a link fails, the link a customer premise device is to use for an application may be, and sometimes is, changed.

The scheduler at the network node also receives information about planned system maintenance. The scheduler takes this information into account when scheduling communications and indicates to the customer premises devices to switch to the link which will not be affected by the maintenance when the maintenance will result in an interruption to service provided via a particular link. For example if a customer premises is to have work preformed on the cable or cable modem at the customer premises, the customer premises device at the customer premises has its communications schedule updated to switch all applications to the wireless link between the customer premises and the network node before the applications at the customer node are affected by the scheduled maintenance. In this way maintenance on the cable modem and/or wireless communications links can be scheduled without service interruptions to an individual customer or customers.

It should be apparent that the joint wireless/cable modem communications scheduling approach on a per application and customer premises basis allows for a wide degree of flexibility in terms of link load balancing at a network node while facilitating network resiliency and maintenance.

An exemplary communications method, in accordance with some embodiments, comprises: operating a network node including a communications scheduler to generate a first communications schedule used to control communications with a first customer premises via both a wireless interface and a cable modem interface; and transmitting or receiving communications from the first customer premises via at least one of said wireless interface and said cable modem interface in accordance with the generated first communications schedule.

FIG. 2, comprising the combination of FIG. 2A and FIG. 2B, is a flowchart 200 of an exemplary communications method in accordance with an exemplary embodiment. Operation starts in step 202 in which a network node, e.g., network node 102 of system 100 of FIG. 1, is powered on and initialized. Operation proceeds from step 202 to step 204, in which the network node stores application information including information indicating one or more applications for which communications are to be scheduled for a first customer premises, e.g., for customer premises 1 105. Operation proceeds from step 204 to step 206.

In step 206, the network node including a communications scheduler is operated to generate a first communication schedule used to control communications with the first customer premises via both a wireless interface, e.g., wireless interface 118, and a cable modem interface, e.g., cable modem interface 120. In some embodiments, the first communications schedule includes information on a per application and per customer premises basis indicating whether an application is to use the wireless interface or cable modem interface for a scheduled communications time period. In some such embodiments, the first communications schedule includes an uplink schedule portion and a downlink schedule portion, said uplink schedule portion including one or more identifiers, said one or more identifiers indentifying on a per application basis one of the wireless interface or cable module interface to be used by the first customer premises for uplink communications corresponding to a first application.

In one exemplary embodiment, the first application is a HD video content creation application and the first uplink identifier identifies that the wireless interface is the interface to be used for uplink communications corresponding to the first application. For example, the first application may be a HD video content creation application and wireless interface uplink may be used for transmission of content created for the application because of large size, e.g., when content is posted to a content distributer or sent to another party for further editing/processing. In some embodiments, the uplink schedule portion of the first communications schedule further includes a second uplink identifier indentifying one of the wireless interface or cable modem interface to be used by the first customer premises for uplink communications corresponding to a second application, e.g., an Internet web browser or voice call application. In some embodiments, the second uplink identifier in the first communications schedule indicates that uplink communications corresponding to the second application will be send using the cable modem.

In some embodiments, the downlink schedule portion of the first communications schedule includes a first downlink identifier that identifies one of the one of the wireless interface or cable modem interface to be used for downlink communications corresponding to the first application, the identified one of the wireless interface or cable modem interface to be used for downlink communications for the first application being the same or different than the identified one of the wireless interface or cable modem interface to be used for uplink communications for the first application. In some such embodiments, the downlink schedule portion includes a second downlink identifier that identifies one of the one of the wireless interface or cable modem interface to be used for downlink communications corresponding to the second application, the identified one of the wireless interface or cable modem interface to be used for downlink communications for the second application being the same or different than the identified one of the wireless interface or cable modem interface to be used for uplink communications for the second application. Operation proceeds from step 206 to step 208.

In step 208 the network node transmits or receives communications from the first customer premises via at least one of said wireless interface and said cable modem interface in accordance with the generated first communications schedule. Operation proceeds from step 208 to step 210.

In step 210 the network node receives cable modem communications link quality information from the first customer premises. Cable modem communications link quality information includes, e.g., feedback information such as packet error rate or interference measurement information sent via the cable modem and/or over the wireless link providing interference information and/or error rate information for the cable modem downlink. In some embodiments, the network node measures the uplink channel quality for the cable modem communications link with the first customer premises based on the interference it detects. Operation proceeds from step 210 to step 212.

In step 212 the network node is operated to receive wireless channel quality information from the first customer premises. The received wireless channel quality information includes, e.g., downlink quality information such as interference information and/or error rate information for the wireless downlink sent as feedback information over the wireless connection or over the cable modem link to the network node. In various embodiments, feedback for either link, wireless link or cable modem link can, and sometimes does, go over the other link in addition to the link to which the feedback relates. In some embodiments, the network node measures the uplink channel quality for the wireless communications link with the first customer premises based on the interference it detects. Operation proceeds from step 212 to step 214.

In step 214 the communications scheduler is operated to make, e.g., generate, a second communications schedule for the first customer premises based on communications link quality information corresponding to the first customer premises, said link quality information including at least one of: wireless downlink quality information, cable modem downlink quality information, wireless uplink quality information, or wireless downlink quality information.

In some embodiments, the communications link quality indicates a degradation of link quality on the cable modem communications link and the generated second communications schedule includes an indicator indicating that at least one of the first and second applications at the first customer premises is to switch from the cable modem communications link to the wireless communications link for at least one of uplink and downlink communications corresponding to the first application. For example, by including a different link indicator than in the first communications schedule for a particular application/communications direction in the second communications schedule, the scheduler indicates the change. For example, an indicator is changed from indicating cable modem communications link to wireless communications link for at least one of the first and second application for at least one of the uplink and downlink, in response to a detected degradation in link quality on the cable modem communications link. As another example an indicator is changed from indicating the wireless communications link to cable modem communications link for at least one application for at least one of the uplink and downlink, in response to a detected degradation in link quality on the wireless communications link.

In some embodiments, an indicated degradation in link quality indicates increased interference on the link or a complete failure in the link. In some such embodiments, in response to a degradation level above an acceptable threshold for the cable modem link or a complete failure of the cable modem link, the indicators are set for each of the applications to indicate that the wireless communications link is to be used. In some such embodiments, in response to a degradation level above an acceptable threshold for the wireless link or a complete failure of the wireless link, the indicators are set for each of the applications to indicate that the cable modem communications link is to be used. Operation proceeds from step 214 to step 216.

In step 216 the network node is operated to transmit or receive communications from the first customer premises via at least one of said wireless interface and said cable modem interface in accordance with the generated second communications schedule. Operation proceeds from step 216, via connecting node A 218, to step 220.

In step 220 the network node is operated to receive information indicating a time period in which scheduled maintenance is to be performed with regard to the cable modem communications link with the first customer premises and the wireless communications link with the first customer premises. Operation proceeds from step 220 to step 222.

In step 222 the communications scheduler is operated to generate a third communications schedule indicating that the first and second applications are to use the communications link on which maintenance is not scheduled during the period of time in which maintenance is scheduled for the other communications link. Operation proceeds from step 222 to step 224.

In step 224 the network node is operated to transmit or receive communications from the first customer premises via at least one of said wireless interface and said cable modem interface in accordance with the generated third communications schedule. Operation proceeds from step 224 to step 226.

In step 226 the network node is operated to receive link loading information corresponding to one or more customer premises. Step 226 includes step 228 and, in some embodiments step 230. In step 228 the network node is operated to receive link loading information for one or more of the wireless communications uplink and the cable modem uplink from the first customer premises. In some embodiments, receiving the link loading information includes receiving uplink queue information for one or more applications and links via the wireless communications link and/or cable modem communications link.

In step 230 the network node is operated to receive link loading information for one or more of a wireless communications uplink and a cable modem uplink from a second customer premises. Operation proceeds from step 226 to step 232.

In step 232 the network node, e.g., the network node communication scheduler, is operated to make a fourth communications schedule based on link loading information. Step 232 may, and sometime does, include one or both of steps 234 and 236. In step 234 the network node is operated to change the communications link to be used for one of the first and second application, e.g., with regard to the first customer premises, in response to a change in link loading. In step 236 the network node is operated to make a scheduling decision based on link loading information corresponding to a plurality of customer premises which share the same wireless communications channel with the access point with which the first customer premises communicates wirelessly. Operation proceeds from step 232 to step 238.

In step 238 the network node transmits or receives communications from the first customer premises via at least one of said wireless interface and said cable modem interface in accordance with the fourth communications schedule.

Different communications schedules may cover different time periods. A communications schedule may be generated, e.g., by scheduler 124, in response to and/or may reflect changing conditions, e.g., a change in application being used, a change in channel conditions, a change in loading conditions, a detected failure, a degradation in a communication link quality, scheduled maintenance time periods, etc. In various embodiments a generated communications schedule is communicated to the customer premises. In one exemplary embodiment, CS 1 448 in network node 102 is the same as CS1 167 in CPE device 1 104; CS 1 448 in network node 102 is the same as CS2 168 in CPE device 1 104; and CS N 448 in network node 102 is the same as CSN 169 in CPE device 1 104.

FIG. 5, comprising the combination of FIG. 5A and FIG. 5B, is a flowchart 500 of an exemplary communications method in accordance with an exemplary embodiment. Operation starts in step 502 in which a network node, e.g., network node 102 of system 100 of FIG. 1, is powered on and initialized. Operation proceeds from step 502 to: step 504, step 508, step 510, step 512, step 514, step 516, step 518, step 522 via connecting node A 520, step 526 via connecting node B 524, step 530 via connecting node C 528, step 534 via connecting node D 532, and step 538 via connecting node E 536.

In step 504 the network node is operated to receive application information indicating one or more applications for which communications are to be scheduled with a first customer premises. Operation proceeds from step 504 to step 506 in which the network node stores application information indicating one or more applications for which communications are to be scheduled with the first customer premises.

In step 508 the network node is operated to received cable modem communications link quality information from the first customer premises, e.g., for the cable modem downlink. For example, feedback information such as packet error rate or interference measurement is sent via the cable modem or over the wireless link providing interference information and/or error rate information for the cable modem downlink.

In step 510 the network node is operated to receive wireless channel quality information from the first customer premises, e.g., for the wireless downlink. For example, downlink quality information such as interference information and/or error rate information for the wireless downlink is sent as feedback information from the first customer premises over the wireless connection and/or over the cable modem link to the network node. Thus, the feedback for the wireless link can go over either link, e.g. can go over the other link, e.g., cable modem link, in addition or in place of going over the wireless link to which the feedback relates. This facilities link quality information regarding a poor quality wireless link being communicated to the network node, e.g., by using a good quality modem link.

In step 512 the network node is operated to measure cable modem uplink communications link quality for the cable module uplink communications channel between the network node and the first customer premises, e.g., based on interference it detects.

In step 514 the network node is operated to measure wireless uplink communications link quality for the wireless uplink communications channel between the network node and the first customer premises, e.g., based on interference it detected.

In step 516 the network node is operated to receive link load information corresponding to one or more customer premises including the first customer premises. For example, the network node receives uplink queue information for one or more applications and links via the wireless communications link and/or cable modem communications link.

In step 518 the network node is operated to receive information indicating a time period in which scheduled maintenance is to be performed with regard to at least one of the cable modem communications link with the first customer premises and the wireless communications link with the first customer premises.

In step 522 the network node is operated to receive information indicating a failure of the cable modem communications channel between the network node and the first customer premises.

In step 526 the network node is operated to receive information indicating a failure of the wireless communications channel between the network node and the first customer premises.

In step 530 the network node is operated to determine that there is a failure of the cable mode communications channel between the network node and the first customer premises, e.g., based on a self test.

In step 534 the network node is operated to determine that there is a failure of the wireless communications channel between the network node and the first customer premises, e.g., based on a self test.

Steps 504, 506, 508, 510, 512, 514, 516, 518, 522, 526, 530 and 532 are performed on an ongoing, e.g., recurring basis, e.g., in response to new information. Different ones of steps 504, 506, 508, 510, 512, 514, 516, 518, 522, 526, 530 and 532 may be performed at different times and/or different rates.

In step 538 the network node including a communications scheduler is operated to generate a communications schedule used to control communications with a first customer premises via both a wireless interface and a cable modem interface. Step 538 is performed on a recurring basis, e.g., generating a new, e.g. different, communications schedule to be used, e.g., in response in a detected change in applications used, loading, channel condition, a detected failure, and/or scheduled maintenance.

Step 540 includes step 542, in which the communications scheduler is operated to generate a communications schedule based on one or more of: applications in use by the first customer premises, received cable modem link quality information, measured cable modem link quality information, received wireless channel quality information, measured wireless channel quality information, received link load information, determined link load information, received cable modem maintenance information, received wireless maintenance information, a detected cable modem channel failure, or a detected wireless communications channel failure.

Step 542 may, and sometimes does, include one or more of steps 542, 544 and 546. In some embodiments, different ones of steps 542, 544 and 546 are performed in different iterations of step 540.

In step 542 the communications scheduler is operated to generate a communications schedule for the first communications premises based on communications link quality information corresponding to the first customer premises, said link quality information including at least one of: wireless downlink quality information, cable modem downlink quality information, wireless uplink link quality information, or wireless downlink link quality information.

In step 544 the communications scheduler is operated to generate a communications schedule indicating that the first and second applications are to use the communications link on which maintenance is not scheduled during the period of time maintenance is scheduled for the other communications link.

In step 546 the communications scheduler is operated to generate a communications schedule based on link loading information. In some embodiments, step 546 includes one or both of step 548 and 550. In step 546 the communications scheduler changes the communications uplink to be used for one of the first and second applications in response to a change in link loading. In step 550 the communications scheduler makes a scheduling decision based on link loading information corresponding to a plurality of customer premises which share the same wireless communications channel with the access point with which the first customer premises communications wirelessly.

In some embodiments, a communications schedule includes information on a per application and customer premise basis indicating whether an application is to use the wireless interface or cable mode interface for a scheduled communications time period. FIG. 3 illustrates some exemplary generated communications schedules.

In one exemplary embodiment, a first generated communications schedule includes an uplink schedule portion and a downlink schedule portion, said uplink schedule portion including one or more identifiers, said one or more identifiers indentifying on a per application basis one of the wireless interface or cable module interface to be used by the first customer premises for uplink communications corresponding to a first application. For example, the first application may be a HD video content creation application and wireless interface uplink may be used for transmission of content created for the application because of large size, e.g., when content is posted to a content distributer or sent to another party for further editing/processing. In some embodiments, said uplink schedule portion further includes a second uplink identifier indentifying one of the wireless interface or cable modem interface to be used by the first customer premises for uplink communications corresponding to a second application, e.g., Internet web browser or voice call application, and second application communications will be sent using cable modem. In one embodiment, the first application is a HD video content creation application and said first uplink identifier identifies the wireless interface as the interface to be used for uplink communications corresponding to the first application.

In some embodiments, the downlink schedule portion includes a first downlink identifier that identifies one of the one of the wireless interface or cable modem interface to be used for downlink communications corresponding to the first application, the identified one of the wireless interface or cable modem interface to be used for downlink communications for the first application being the same or different than the identified one of the wireless interface or cable modem interface to be used for uplink communications for the first application. In some such embodiments, the downlink schedule portion includes a second downlink identifier that identifies one of the one of the wireless interface or cable modem interface to be used for downlink communications corresponding to the second application, the identified one of the wireless interface or cable modem interface to be used for downlink communications for the second application being the same or different than the identified one of the wireless interface or cable modem interface to be used for uplink communications for the second application.

In one embodiment, during one iteration of generating a communications schedule, the communications link quality, e.g. used as an input in the scheduling decision, indicates a degradation of link quality on the cable modem communications link and a communications schedule, e.g., a second communications schedule, is generated which includes an indicator indicating that at least one of the first and second applications at the first customer premises is to switch from the cable modem communications link to the wireless communications link for at least one of uplink and downlink communications corresponding to the first application, e.g., by including a different link indicator than in the first schedule the schedule indicates the change. In some such embodiments, the indicated degradation of link quality indicates increased interference on the link or a complete failure of the communications link. In some such embodiments, if the link quality indicates a complete failure of the communications link none of the applications are assigned to used the failed link, e.g., the applications are offloaded to the still properly operating link.

Operation proceeds from step 538 to step 554, in which the network node is operated to communicate the generated communications schedule to the first customer premises. Operation proceeds from step 554 to step 556, in which the network node is operated to transmit or receive communications from the first customer premises via at least one of said wireless interface and said cable modem interface in accordance with the generated communications schedule.
